I recently got a 32" Westington VR-3225 TV to use as a display for my computer. I connected my machine to the TV using an HDMI cable, and for the most part, it looks great. However, there is a small issue with some fonts where a small white line appears in gray areas, particularly with letters with straight horizontal lines such as A, H, F, etc. I tried using multiple machines with different video cards and the problem persists, suggesting that the problem lies with the display.

It was hard to capture an image of the issue, so I tried to recreate what it looks like in GIMP.

Does anyone know what could be happening here and how to fix it? I know it's a relatively small annoyance, but it would be great to fix

While cleartype seems to make text slightly better overall, the issue still occurs. Changing display settings on the TV didn't affect things noticibly.

To me, it seems like an anti-aliasing issue with the gray parts of the font. What might be the problem is 4:4:4 display. While this TV is supposed to be capable of 4:4:4, running some visual tests such as the ones found at http:// www. avsforum .com/avs-vb/showthread.php?t=1371234 (sorry about the spaced url, I have to make 3 posts before I can actually link and the reply auto-detects urls >_>) makes me doubtful of a true 4:4:4 output.

Any thoughts?

If you are using a Nvidia card, you will likely need to do the EDID overide. You can find out how to do that here if you are unsure how to do it.

I also have a concern about how you might be viewing the test image. Please make sure you are viewing it in one of the ways below to rule out a "scaling" issue:

On a non-4:4:4 TV, the red/cyan columns will have alternating thickness - some would be 1 pixel wide while others would be 2-3 pixels wide. Note: for the Bell-Nuit test, you may need a magnifying glass or macro lens to see the pixel widths clearly.

WMI (Windows Image Viewer) needs to have it's window maximized (make sure it's not zoomed in) or, you can click "fit image to window" (Ctrl+O) if you don't have the window maximized. It will not display the test image correctly if you don't do one of those two options.

MPC HCE (Media Player Classic Home Cinema Edition) needs to either have the window maximized or, it needs to be in full screen mode. It will not display the test image correctly if you don't do one of those two options.

WMP (WIndows Media Player) needs to either have the window maximized or, it needs to be in full screen mode. It will not display the test image correctly if you don't do one of those two options.

On a non-4:4:4 TV, pixels will appear faded and/or duplicated -- this is most noticeable with the red, blue, and magenta lines.

MPC HCE (Media Player Classic Home Cinema Edition) can not display the "bspvette86" test image as it can not render png files.

WMP (WIndows Media Player) needs to be left alone when you open the test image in it. If you maximize the window or enter full screen mode, it will improperly scale the test image.

Describing quality differences through words is difficult, so I will let pictures do the talking instead. Here are some A/B comparisons between 4:4:4 and non-4:4:4. All pictures were taken under identical conditions without any post-manipulation (except a resize function).

From the examples, you can clearly see quality differences (except for the real life image). The differences are even more pronounced in-person. So is 4:4:4 a necessity? I certainly think so, especially when it comes to text.
